One, 1.1 what is Python Python is an elegant and robust programming language that inherits the power and versatility of the traditional compiler language, as well as the ease of use of simple scripts and interpreting languages. It can help you get the job done, and after a while you'll be able to see the code you've written. You'll be amazed at how quickly you learn it and its powerful features, not to mention the work you've done. Only you can't imagine, no Python. Two, 2 1.2 origins Fan Ross

of data cleaning and data conversion is achieved by setting up the visual function node of data processing beforehand. For data reduction and integration, a variety of data processing function nodes are provided through the combination preprocessing subsystem, which can quickly and efficiently complete data cleaning and data conversion process in a visual way. 4.

, whether it is open source or commercial ETL tools have their own job scheduling, but from the use of flexibility and simplicity, it is not as good as the third-party professional to do batch job scheduling tools. Since they are all tools to facilitate the use of people, why not use better tools to relieve our workload, so that we can devote more effort to the business itself. Here is to share a third party open source batch job Automation tool TASKCTL (open source Community address: https://ww

, dimension tables, summary tables, etc. New data needs to be updated to these tables on a daily basis. The procedures for updating these tables (programs) are developed at the very beginning, and each day only needs to pass some parameters, such as dates, to run the programs. 3. Data loading: Personally, each insert data to a table, can be called data loading, as for Delete+insert, Truncate+insert, or merge, which is determined by the business rules, which are embedded in the data extraction an

Today, I'm going to explain a tutorial on C + + for everyone. I will be writing this tutorial when I have time.The purpose of this tutorial is two:1. Easy to understand. When I was learning C + +, I didn't find a simple tutorial on the whole internet. In the end, I found a suitable tutorial in the bookstore, but it took a long time to learn it. I don't want readers to repeat my mistakes, so it's one of my purposes to be easy to understand.2. Cut the crap. Nonsense will waste you and my time, lea
